Build instructions

If you would like to develop this application we'd love your help! These build instructions are brief and should be improved, please send a PR if you can.

• Use Android Studio 4.1.2 to build/debug (other versions might work but no promises)
• Use git submodule update --init --recursive to pull in the various submodules we depend on
• There are a few config files which you'll need to copy from templates included in the project. Run the following commands to do so:

        rm ./app/google-services.json
        cp ./app/google-services-example.json ./app/google-services.json
        rm ./app/src/main/res/values/mapbox-token.xml
        cp ./app/special/mapbox-token.xml ./app/src/main/res/values/
        rm ./app/src/main/res/values/curfirmwareversion.xml
        cp ./app/special/curfirmwareversion.xml ./app/src/main/res/values/

• (Unfortunately) you need to get a (free) mapbox developer token here and put that token in your user gradle.properties.

~/development/meshtastic/MeshUtil$ cat ~/.gradle/gradle.properties
MAPBOX_DOWNLOADS_TOKEN=sk.yourtokenherexxx

• Now you should be able to select "Run / Run" in the IDE and it will happily start running on your phone or the emulator.

:::note The emulators don't support Bluetooth, so some features can not be used in that environment. :::

Analytics setup

• Analytics are included but can be disabled by the user on the settings screen
• On dev devices

adb shell setprop debug.firebase.analytics.app com.geeksville.mesh
adb shell setprop log.tag.FirebaseCrashlytics DEBUG

for verbose logging:

adb shell setprop log.tag.FA VERBOSE

Publishing to google play
